Driving a semi-truck, school bus, or other commercial vehicle is a great way to make a living in Oklahoma—but in order to do so, you will first have to get your OK commercial driver's license (CDL). Since these types of vehicles are larger and typically more difficult to operate than average cars and trucks, getting a CDL is a bit more involved than applying for a regular driver's license.

For a full list of acceptable documents, see the Oklahoma Department of Public Safety's page on CDL ID requirements.

Per rules set by the FMCSA, CDL drivers under 21 years old are only permitted to drive commercial vehicles within Oklahoma.

Commercial Learner's Permits in OK

Before you can get your CDL in Oklahoma, you'll have to get your commercial learner's permit (CLP). You may want to look into a commercial driver license training course to help you pass all the necessary tests.

Your driving record for the past10 years in all 50 states and Washington, D.C. will be checked while at your appointment.

You will also have to fill out any paperwork or applications given to you at the Oklahoma Department of Public Safety.

Take the appropriate written exams for the type of CDL you're applying for. Once you pass them, you will be issued your Oklahoma commercial learner's permit.

Oklahoma CLP Restrictions

The Federal Motor Carrier Safety Administration requires all CLP holders to have their commercial learner's permit for at least 14 days before applying for a full CDL.

While driving with your CLP, you will also be restricted to driving on public roads, with a full CDL holder accompanying you.

Oklahoma CDL Classifications

There are several different classes of CDL designated by the FMCSA, each of which giving you permission to drive different types of commercial vehicles in Oklahoma, including:

Class A CDL—Allows you to operate multiple vehicles over a certain weight, such as a tractor-trailer.

Class B CDL—Permits you to drive a single vehicle over a certain weight, like a box truck.

Class C CDL—Applies to all other types of commercial vehicle not covered by Class A or Class B CDLs.

Depending on the type of commercial driver's license you apply for, you will have to take different written and skill exams and pay slightly different fees to the OK Department of Public Safety.
